Ordovician Marrellomorph from Ontario

[MarcusFossils]

I found this specimen in 2020 and donated it to the Royal Ontario Museum later that year. A paper is to be published very soon formally describing it! It's a roughly 7cm wide mimetasterid marrellomorph - the only marrellomorph know from the Ordovician of Canada, and one of a handful of such arthropods recorded worldwide. 

 

 

I found my very first trilobite in 2014. The members of this forum helped my ID it, learn more about the stratigraphy of my area and what tools to use to find more. Thanks to that base of knowledge,, the last 7 years have seen paleontology become an increasingly important part of my life. This incredible fossil in the culmination of what started right here on TFF- so thank you!

Thanks Don! This one comes from the Bobcaygeon Formation (or Kirkfield, depending the source).
